What's going on guys?
My, name is colin, ross welcome back to another tutorial today i'm gonna be giving you an overview
Of, my, 3d workflow how i go from after effects to buzu to 3ds max and then back to after effects
So i'm not, gonna be showing you how, to achieve the effect. You just saw rather than be showing
You, the process i took to achieve that result real quick again just before we start we're starting in after effects then
We're, going into buju worth
3d motion tracking then we're
Exporting that 3d camera to 3ds max and rendering out an object that we're then, going to bring back into after effects
To, make it look
Like it's actually a part of our scene to get started once you have your composition trimmed up to the length that you want
While you're in your composition hit ctrl m and it's going to bring up at the render queue click right here
Where it says lossless and then right under here where it says format we're
Going to change the format to an image sequence and we're, gonna pick jpeg sequence click format options
And drag it to like 8 or 9 it doesn't have to be the highest quality but
We still want a good quality image for your motion tracking and if you click this right here you can
Change the file destination your rendering at, so i'm going to go here and in here my
3d workflow, so i'm gonna create a, new folder called tutorial
Enter it hit new folder and change it to seek this is short for sequence we're
Gonna, click here and then you know just name the file tutorial and this is gonna keep everything organized
This is about to render out an image sequence and all the images are about to be stored in this folder click save and
Then hit render
So once that's done open up buju here, and right here under the tool, box click import sequence we're
Going to navigate to where our source footage is so mine is in the e drive under my
3d workflow under tutorial seek and then click the first image
And that'll import your entire image sequence this is where you have to decide what move type your camera
Was moving in this instance the camera, was moving in 3d space so we're, gonna be doing a?
Free move track compared to if you, were panning on a tripod that's a
Nodal pan basically if your camera is on a tripod
Click, nodal pan and if your camera is free moving hit, free move pretty simple you, want to make sure you
Have the same frame rate selected that your source footage was shot in you can go into after effects
And see right here that, my footage was shot in 23.976
Go, back into buzu, change this to 23.976
Hit apply for whatever reason, bougie has a little glitch right here and it changes the frame rate back to 25
Just hit that and change in 23.976
again
Hit apply
And then click close the reason i create an image sequence is because buju doesn't track
H.264 files as good as it does image sequences so the first, thing i'm gonna do is add a
Poly, mask right here in the very far distance of my, image this you're, gonna, make, sure that it's gonna attract
More of what's in my foreground because i want to add something right here on the bridge i don't want to add anything in the
background
also
gonna Bump up the contrast over here so it's a little easier for the tracker to pick up all the contrast in the image
I'm gonna hit track features
Advanced i'm gonna change the sensitivity all the way up change the max search distance to 50% hit start it's gonna
Do its best to put a bunch of tracking markers in your scene and try and figure out, what the camera
Was doing in real life
Now that that's done when you script through your foot as you can see boozers does a really good job at holding on to all
These points in your, scene but, what you want to do to help it out
Before you try to solve the camera this this hasn't created, a 3d camera in your scene i'm gonna
Pick a couple points that i think are grabbing on to the scene
Well i'm gonna click one hold down ctrl and then continually clicking other points that i think are tracking, well to the scene
Some further in the background
Some closer some off to the left over here don't click too many the more you click the longer it's going to take for the
computer to track your camera, so i'm gonna, maybe click like 8 9
10 right click one of them and click gold this is going to tell buju that
These are great tracks and use them as reference for the other tracks i'm gonna go up to
3d tasks hit solve camera optimized camera path smoothest, and then hit start let it do its thing again this is a little bit quicker
Usually if it isn't too difficult of a solve and boom now
You can, see all those track features were turned into actual
3d data points this, is kind of hard to see just from a
2d image but if you go up here and click 3d if you hold shift and left mouse click you can kind of rotate around
This, 3d image and you can see that the camera is here here all these
3d points in space so i'm gonna drag it up so it's almost like an orthographic. View point i'm gonna
Click this button right here so i can edit the coordinate system and then hit the rotate and then i'm gonna drag
Along the red here so if you go, back into the 2d space, and select points on the plane
You're!
Trying to add an object to and then go back to the 3d you can see where all those points are selected i want to
move these points
So they're at the original coordinate system after i've rotated i'm gonna go to the move
And then move these over and then down if you shift click and right-click you can
Zoom into the image so you can, see more detailed drag this up shift left click again
and drag around drag this to the coordinate point zero zero
Right here in the middle and that is looking good now that, we have our camera match move how are?
We going to get those in just as a camera in 3ds max and then add objects to our scene there and it's pretty simple
All you have to do is go up to the export tab up here export camera
Solve but this is where whatever?
3d program you're deciding to use you, would just select, so i'm using
3ds max if you're exporting back to after-effects you can, do after-effects but i'm using
3ds max so i'm gonna click that and then you
Want to unselect use format default for start index null size hit zero and then click scale scene by 100 this again
The scale your scene up just a little bit so once you, do that browse to where you, want to save
Your, file i'm gonna, do it again in my, 3d workflow
And in the tutorial folder i'm gonna create a, new folder called buzu
And i'm exporting the camera hit save and then that should save your camera as a script so then we're
Gonna, go in 3ds max so, we saved a max script out of buju that contains all the camera data that we're
Gonna import so, we want to go up to scripting run, script navigate to your file - in you know
Tutorial, buzu, click the maxscript but, what you're
Gonna see there's a syntax error in a little bit of the script but
You just have to edit a little bit whatever reason buzu includes a piece of image sequence that doesn't work with 3ds max so you
Just have to click, ok select here and drag up to the point, where it says file name and there's hit
Backspace click file save and then exit out scripting and just run the script again
And it'll work just fine this just imported a. 3d camera into
3ds max just like the one we had in buju
And what i do here is i select every single point i go up here to group and hit group, again
And then rename it camera what i also, do with the camera selected here is go up to the hierarchy
And affect the pivot point to be here in the original origin at 0 0 this just gonna make it scale and rotate around
the plane that
We want to i know this is a lot of information coming at you very fast i because a lot of people subscribe this channel
Just, want after effects. Tutorials and they might not be interested in this i just wanted to share my workflow
In case, you guys were interested in learning this because but if this is something you're interested in comment down below
And i'll try to help you out as much as i can i realize there's so many steps there's so many
New things to learn, when you're working with
3d but now, what we're?
gonna do
Is we're going to i always select the bottom right quadrant i'm gonna hit shift f and this is going to make it so it
Displays the actual aspect, ratio of my, camera
And right here where it says
Perspective on it click cameras and then go into
My camera if i hit alt w and 3dsmax it will maximize the viewport i'm hovering over you can kind of see that the camera
Is moving just how it did in buju and then what i want to do is i want to hit alt b and change the
Background to a file image map i'm gonna click use files
animate background go here to files and
Browse and select the image sequence that we already rendered out of after effects
And then i'm gonna get the first image and then click sequence hit open
Okay, apply to active view so we're up to the point, where you have this image in our background
And we have our camera imported and it's all lined up since we're trying to add something to this road right here
We want to do is align this coordinate system to be like it's on the plane of this road i'm gonna rotate this so it's
Going at the same angle this road and i'm gonna hit select the uniform scale and scale this up
So that the grid is scaled down and as you can see and that looks like
There's a grid on the road that's perfectly tracked in our scene now anything that
We draw and create in 3ds max will be tracked to the scene let's say
I, want to add a few pyramids?
So i'm gonna
Add one here so because i imported my camera everything is going to be correctly on
This, plane, so as you can see as you drag through it should be properly tracked, who you're seeing
Which is pretty darn cool
So now how are we gonna render this and bring it into after effects in the the answer to this is an image sequence with
alpha
So we're gonna go up to render hit render setup i'm just gonna do the traditional
Scanline renderer because it's the quickest it's not gonna be good quality i'm gonna change the width
And height to 1080 just to save some time i'm gonna, go to files i'm gonna, name this
Tutorial, and then where it says save
As type i'm gonna hit png image sequence i'm gonna hit save and then right here just click rgb
48-bit and make sure you preserve the alpha channel so when you, bring it into after-effects there's no background
And then make sure the active time segment, is selected so it renders for every single frame in the sequence
And i'm just going to render
So once that's done hop, back into after effects and this is the easy part click file import
File and then navigate to what we just rendered colin 2017 my, three workflow
Tutorial hope i accidentally saved the render
Outside here so go into your render hit the first image in your sequence make sure a png sequence is
Selected here and then click import then
You, want to right click this and click interpret footage, main and then change it to whatever frame rate your sequence
Was this trip, me up for the longest time because nothing, would stay tracked correctly but then i realized
It wasn't playing at the frame rate that i rendered it so just click
23.976
I'm gonna
Drag this on top of our footage since i rendered out at 1080p m and have to scale it up to 200%
If you render through there everything, is tracked. And that is pretty much the completed
3d workflow of how i go from after effects to tracking in buzu and then
Importing that to 3ds max and rendering out in animation hopefully you enjoyed this insight to how
i create
Some of the visual effects that i do on the shorts on this channel if you found, this video
Informational if you liked it leave, me a like if you didn't leave
me a dislike and let me know how i can improve my tutorials
My videos in the future and as always subscribe if you, enjoy, my, content i'll see you guys, tomorrow i'm uploading video every single
Day for the rest of 2017. Piece-by-piece peace
